201003204 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a liquid crystal display device and an electronic device. [Prior Art] A light modulating device of various photoelectric devices uses a liquid crystal display device. The liquid crystal display device mostly has a difference in optical path length when light penetrates the inside of I, and a complex refractive index difference of a plurality of materials constituting the device, and a phase difference occurs in the transmitted light, and blurring and bleeding occur in the displayed image. Improper waiting. Therefore, it is generally necessary to optically compensate for the "phase difference" in various ways. For the fourth phase of the complex refractive index, it is known that the phase difference layer for eliminating the phase difference is provided. This Lixin crystal display device - tooth J 1 is the reflection type of the light after the modulation of the gums + *, soil. The body is not a method, and the other side of the incident side is different from the incident side of the light. The display method of the penetrating type of the latter light. Further learning = halving the transflective liquid crystal of two display modes. The transflective liquid crystal display device uses any of the display modes of the reflection mode or the penetration mode by the brightness of the surroundings. , and has the ability to reduce power consumption, and that is to use the strength of the fixed. p makes it possible to clearly display the surrounding darkness. This transflective liquid crystal display device performs the penetration in the reflective display area and does not perform homogenous display for optical compensation. ^ Image n is often carried out by a so-called multi-gap structure by using a liquid crystal layer thickness adjustment layer having a thickness of a liquid crystal layer which is thicker than a liquid crystal layer of a 139010.doc 201003204 transmissive display region. To eliminate the optical path difference between the reflective display area and the transparent display area. Patent Documents 1 to 4 disclose a structure in which the thickness of the liquid crystal layer is controlled by a spacer disposed on the liquid crystal layer thickness adjusting layer in addition to the multi-gap structure. Further, Patent Documents 5 and 6 disclose a configuration in which a phase difference layer is provided on a color filter layer, and a phase difference layer is further used as a multi-gap structure to optically compensate to eliminate a phase difference.

In the configuration in which the spacer is disposed on the adjustment layer, a new problem arises when a structure in which the phase difference layer is optically compensated as the liquid crystal layer thickness adjustment layer is applied. In general, the retardation layer uses a liquid crystal having refractive index anisotropy as a forming material. The retardation layer is low in hardness due to the properties of the liquid crystal polymer. Therefore, when the stress applied to the liquid crystal display device is transmitted to the liquid crystal layer thickness adjustment layer via the spacer, since the hardness of the phase difference layer is low, the liquid crystal layer thickness adjustment layer is liable to collapse in the phase difference layer, and it is difficult to manage a certain layer thickness. Similarly, when the object is in direct contact with the retardation layer, the spacer collapses easily in the optical path length image in the retardation layer 'liquid crystal layer'. Easy to branch, thus showing the invention, the invention is based on the hardness of the phase difference layer of the case, "providing a kind of liquid crystal layer thickness management by suppressing β 所 s s, a The liquid crystal display device which displays the image display of the ancient mouth is provided with an electronic device including the liquid θ 1:1, and the object of the present invention is a night crystal display device. [Means for Solving the Problems] In order to solve the above problems, the present invention, the sixth substrate, and the second substrate and the second panel 1' are characterized by a cladding layer sandwiched between the first substrate And the first two, the liquid crystal layer, which is disposed between the front Μ-substrate; the phase difference sign... the liquid crystal layer side of the substrate, the protective layer, which covers the phase difference layer and the first october a side surface of the phase difference layer connected to the surface, and a side surface of the phase difference layer connected to the surface, and a spacer surface disposed between the surface layer and the spacer layer The first substrate and the second substrate are kept at a certain interval apart from each other; and the protective layer exhibits a higher hardness than the phase difference layer. According to this configuration, the portion where the spacer is disposed is covered with a protective layer having a higher hardness than the phase difference layer. When an external force is applied to the liquid crystal display device, the stress is dispersed in the retardation layer via the protective layer of high hardness. In addition, since the protective layer having a higher hardness than the phase difference layer is formed in contact with the base surface, in the case where an external force is applied in the same manner, the protective layer covering the side surface acts like a screen or a pillar, and functions as a support member against stress, and is applied to the phase difference layer. The stress is diffused to the base surface via a protective layer covering the side surface of the retardation layer. Since the effect of 139010.doc 201003204 suppresses the deformation of the phase difference layer, and the separation distance between the first substrate and the second substrate can be well controlled by the spacer, the liquid crystal display device capable of achieving high-quality image display can be realized. . In the present invention, the reflective display region is provided in one pixel region to penetrate the display region. The phase difference layer is disposed in the reflective display region. The protective layer covers one pixel region and is located in the reflective display region and the wearing portion. The side surface other than the side surface of the phase difference layer on the boundary of the display region is in contact with the base surface. According to this configuration, the protective layer covers the side surface other than the side surface of the phase difference layer located at the boundary between the reflective display region and the transparent display region, in other words, it is in contact with the substrate surface along the side surrounding the periphery of the reflective display region. Thus, the protective layer forming the covering side is enlarged, and the supporting member used as a wide area against the stress can more strongly suppress the deformation of the phase difference layer. In the present invention, a plurality of the aforementioned pixel regions should be arranged in a direction in which the arrangement of the pixel regions is parallel to the center of the image and the center of the pixel region is too h (four) direction The center line is provided with the reflection display area on one side, and the penetration display area is disposed on the other side, and the phase difference layer is juxtaposed along the arrangement direction of the image +, ten- _ ', and / a plurality of the reflective display regions are formed to form a smear-like shape, and the protective layer covers the surface of the smattered phase, the S... The side surface of the phase difference layer, which is connected to the surface and the center line is described, is touched to the base surface, and is accessed by uq F , and the spacer is disposed at a boundary portion of the adjacent pixel region. In order to use - the height between the objects J. The thickness of the liquid crystal layer 'configuration I3901〇.d〇c 201003204 The thickness of the part of the spacer is yet to be roughly uniform. According to this configuration, the phase difference layer and the protective layer are formed, ', continuous, because it can be stupid. 丄 丄 丄 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( For example, it is possible to improve the initial aperture ratio of the symplectic surface. In addition, it is formed by patterning. The liquid crystal display device is easy to change due to the valley.

In the case of the second embodiment, the spacer should be placed on the opposite side of the through-display region from the center of the reflective display region and extending in parallel with the arrangement direction of the pixel regions. ——According to the structure', since the protective material covering the side of the phase difference layer is disposed at a position close to the plane, the spacer and the body are resistant to stress, and can effectively support the white and the six s θ. The pressure from the outside of the liquid crystal display device. In the present invention, a reflective display region is provided in the <solid pixel region, and the display region 4 is disposed. The phase difference layer is disposed in the reflective display region, and the mask is covered in the first pixel region. The display area and the side of the transparent display area Μ $, +. _J_Q ν β L sighs the side of the side of the phase difference layer, and is in contact with the base surface. According to this configuration, the protective layer includes a side of the boundary between the reflective display region and the through-display region, m surrounding the reflective display region, and the substrate is in contact with the substrate. Therefore, the deformation of the suppression phase difference layer can be further reduced. In the present invention, the retardation layer is to have a flat surface on a surface facing the first substrate, and the spacer is disposed to overlap the flat surface. When a phase difference layer is formed by patterning using photolithography, the side surface of the phase layer 139010.doc 201003204 may be a phase difference layer having a slope shape and a different thickness, which is provided by the surface layer. Liquid crystal layer thickness management. In the present invention, it is possible to arrange the spacers in the present invention. In the present invention, the protective layer should function as the above-mentioned reflective display region, and the member does not have the domain and the front layer. According to this configuration, by appropriately setting the thickness of the phase difference layer of the protective layer, the liquid crystal layer in the layer thickness of the liquid crystal layer in the reflective display region is not changed. The thickness of the layer can be independently controlled as the thickness of the liquid crystal layer to adjust the layer thickness of the liquid crystal layer in the region of the reflective display region, and the phase difference of the light imparted by the poor layer. In the present invention, the phase difference is employed, the y· a λ is formed, and the 5 n θ θ liquid is formed into a material, and the protective layer is formed of an inorganic material. Since the protective layer is formed of an inorganic material, the retardation layer formed by using the liquid crystal compound as a material can additionally improve the hardness of the S layer. In the present invention, the foregoing protective layer should have a spacing or ratio from the foregoing. Its high According to this structure, the deformation of the phase difference layer can be further reduced by suppressing the portion w and the I shape of the protective layer itself. Therefore, in the present invention, the spacer should be provided integrally with the protective layer. According to the structure, in the relationship between the phase difference layer and the protective layer, the liquid crystal layer is managed in a liquid crystal layer, and the spacer layer is formed in advance at a suitable position, and the liquid crystal layer thickness management can be performed satisfactorily at 139010.doc •10·201003204.

The sub-pixel P is divided into two regions in the long-axis direction. The upper region of the figure is a reflective display region R, and the region on the lower side of the figure is worn. The transmissive display area and the transmissive display area have substantially the same shape and size as the planar view and are adjacent to each other in the central portion of the sub-pixel area. Further, the respective reflective display areas between adjacent sub-pixels are similar. The arrangement is arranged along the direction of the short-axis direction of the sub-pixels which are substantially rectangular in plan view. The planar view of the characteristic portion of the present invention is the strip-shaped inner surface phase difference portion 4〇 and the adjacent reflective display region scale flatness. The end of the end portion in the direction orthogonal to the extending direction of the inner surface phase difference portion 40 is in contact with the boundary between the reflective display region R and the through display region τ, and another The image is disposed in the region between the pixels. The figure is a cross-sectional view of the liquid crystal display device i, and is an arrow observation cross-sectional view corresponding to the line AA of Fig. 1. The liquid crystal display device of the present embodiment is in the opposite liquid crystal. The layer 30 applies an electric field component (transverse electric field) in the direction of the substrate surface to the method of controlling the (a) azimuth of the (tetra) crystal material, and adopts the method of performing image display (fourth). In addition, the system includes a color irradiator. The color LCD is set to 'and i pixels are composed of three sub-pixels that emit light of each of R (red), G (green), and B (blue).

In the following description of Fig. 2, the direction in which the backlight 6 is disposed is downward, and the direction in which the counter substrate 20 is placed is upward, and the vertical relationship of each constituent member is displayed. The substrate body i 0A of the element substrate 10 is For example, an inorganic material such as glass or tantalum nitride is formed of a material having optical transparency such as an organic polymer (resin) such as an acrylic resin or a polycarbonate resin or a composite material thereof. An element layer 12 including a driving element, a wiring, and an inorganic material or an organic insulating film which is electrically insulated from the substrate is formed on the substrate body 1A. Each of the wiring and the driving element can be patterned by photolithography, and the insulating film can be suitably formed by a conventional method such as a vapor deposition method or a sputtering method. On the element layer 丨2, a reflective layer 14 is formed by being planarly overlapped with the reflective display region R. The reflective layer 14 is formed with a metal reflective film such as silver or a metal on a resin layer such as an acrylic resin. Since the surface of the resin layer has a concavo-convex shape, and the metal reflective film is formed by reflecting the concavo-convex shape, the entire reflection layer 14 139010.doc -13 - 201003204 constitutes a reflection mechanism having light-scattering properties of the uneven surface. Others, even if a film is selectively formed by a vapor deposition method and a money ore method, a metal film in which silver and a light reflectance are stacked, and a dielectric film having a different refractive index (Si〇2 and Ti〇2) are formed. A dielectric laminated film (dielectric mirror) of the same can be obtained by forming an uneven shape on the surface of the formed film. The progress 'over the element layer 12' covers the reflective layer 14 and the element layer 12, and a common electrode 15 is formed which overlaps the through-display area τ and the reflective display area. The common electrode is formed of a transparent conductive material such as "indium tin oxide". On the common electrode 15, an interlayer insulating film 16 made of an inorganic insulating film such as yttrium oxide is entirely formed on the surface, and an interlayer insulating film is formed on the interlayer electrode. A pixel electrode 17 which is overlapped with the penetrating display region τ and the reflective display region ruler is formed on the pixel 16. The pixel electrode 17 is made of a transparent conductive material such as ΐτο, and has a ladder (open slit) shape or comb in a planar observation state. Further, on the interlayer insulating film 16, an alignment film 18 made of a polyimide or the like is formed on the surface of the pixel electrode 17. Further, the substrate body 2 and the element included in the opposite substrate 20 are formed. Similarly, a substrate having transparency can be used for the substrate body 1 of the substrate 10, and inorganic materials such as glass, quartz glass, and nitrogen cut can be used for the two plates; and an organic polymer such as acrylic acid or polycarbonate resin (resin In addition, when it is optically permeable, it is also possible to form a composite material by stacking or mixing the above materials. In this embodiment, glass is used as the substrate body 20 A color filter layer 22 including a colored 7 2 blackening matrix 22b is formed on a surface of the substrate body 20 on the inner surface side of the device. The color illuminator layer 139010.doc • 14 - 201003204 Light emitted to the front of the device and incident from the front of the device, reflected by the reflective layer 14 and emitted to the front of the device is modulated into red, green, and blue, and can be displayed in full color by mixing the colors of the respective colors. Color; the surface of the inner surface side of the device layer 22 of the optical filter layer 22 is formed with a cover layer (not shown) for physically or chemically protecting the color filter layer 22. Further, the color filter layer 22 may be The inner surface retardation portion 4A of the characteristic portion of the present invention is provided on the surface of the color filter layer 22 on the inner surface side of the device, and is overlapped with the reflective display region R. The inner surface phase difference portion 40 Providing a function as a liquid crystal layer thickness adjusting layer for making the layer thickness of the liquid crystal layer 30 in the reflective display region R thinner than the layer thickness of the liquid crystal layer 30 penetrating the display region D. The liquid crystal layer in the reflective display region ruler 3 〇 layer thickness in the light of the tooth The thickness of the phase difference of λ/4 wavelength is given. The inner surface phase difference portion 40 includes the phase difference layer 42 and the protective layer 44. The phase difference layer 42 is formed to overlap the reflective display region R, and the phase difference layer and the penetrating display region are provided. The end portion of the opposite side is formed to extend to the non-display area DA. The phase difference layer 42 is formed by using a liquid crystal polymer obtained by polymerizing an ultraviolet curable liquid crystal material (liquid crystal monomer or liquid crystal oligomer), and The phase difference layer 42 is a so-called inner surface phase difference layer provided on the inner surface side of the counter substrate 20. The phase difference layer 42 is provided with an image for compensating the display area Τ and a reflective display area. The phase difference of the image is such that the phase difference layer 42 imparts a phase difference of λ/2 wavelength in the transmitted light. Further, a protective layer 44 is formed covering the surface of the phase difference layer 42. The protective layer 44 covers the end portion of the phase difference layer 42 disposed in the non-display area DA, and is formed on the surface of the color filter layer 22 of the base surface of the contact side and retardation layer 42. The protective layer 44 is formed using a material which exhibits a higher hardness than that of the retardation layer 42, and is formed by using a precursor acrylic resin and an epoxy resin as a forming material by a conventionally known method. For photosensitivity, positive or negative can be used as appropriate. Contact with the protective layer 44 formed in the non-display area DA forms a spacer 50 which controls the thickness of the liquid helium. The spacer 5 形成 can be formed using the same material as that of the material for forming the protective layer 44. The shape of the spacer is particularly limited to a columnar shape such as a columnar shape or a polygonal column shape, or a spacer having a wall shape having a large width. The spacer 50 is disposed at a position overlapping the protective layer material, in other words, at the display display region R. When the spacer layer 5 is disposed in the penetration-display area τ, the thickness of the liquid crystal layer 30 in the reflective display area rule is affected by the thickness variation of the inner surface phase difference portion 4〇. In the present embodiment, since the spacer 5 is disposed in the reflective display region R, the layer thickness of the liquid crystal layer % in the reflective display region can be controlled to a specific thickness irrespective of the variation of the thickness of the inner surface retardation portion. . Further, an alignment film 28 is entirely formed on the surface on the inner surface side of the device of the color filter layer 22 so as to cover the surface of the inner phase difference portion 40. The alignment film 28 is an organic alignment yoke formed by using a polySi imine film, and is formed by forming a polyimide film on the color filter layer 22 and the retardation layer 42 and then performing rubbing treatment. Further, the element substrate ί includes a polarizing plate 19 on the side opposite to the liquid crystal layer 30, and the counter substrate 20 includes a polarizing plate on the side opposite to the liquid crystal layer 3'. In the present embodiment, the liquid crystal display device i of the state of 139010.doc •16·201003204 has the above structure. Fig. 3 is a schematic view showing the periphery of the inner surface phase difference portion 40 and the spacer 5'' of the characteristic portion of the present invention. Fig. 3 (4) shows a perspective view, and Fig. 3 (b) shows a cross-sectional view. Fig. 3 (4) shows a plan view. Fig. 3 is a view in which the drawings are easily inverted as shown in Fig. 2 for easy viewing of the drawings. As shown in Fig. 3(a), the inner surface retardation portion 4 is overlapped with the reflective chevron region r included in the sub-pixel p, and extends across the adjacent pixel 延伸 to extend into a strip shape. One end perpendicular to the extending direction is in contact with the boundary of the transmissive display region τ and the reflective display region R, and the other end is planarly overlapped with the non-display region DA of the region between the pixels. The retardation layer 42 included in the inner surface retardation portion 40 is superposed on the reflective display region R in the extending direction of the inner phase retardation portion 4, and extends in a strip shape across the adjacent pixel. One end perpendicular to the direction of the extension direction is in contact with the boundary of the transmissive display region T and the reflective display region R, and the other end is planarly overlapped with the color filter layer 22 of the non-display area DA of the region between the pixels. Similarly, the protective layer 44 is superposed on the reflective display region R in the extending direction of the inner surface retardation portion 4, and extends in a strip shape across the adjacent pixel X. The compliant layer 44 covers the upper portion of the retardation layer 42 and the side portion facing the non-display region DA to form an end portion of the phase difference layer 42 that is in contact with the color concentrator layer 22 along the non-display region ,. It is formed in contact with the color filter layer 22. Since the protective layer 44 is in contact with the color filter layer 22 in the non-display area DA, the contact surface of the protective layer 44 and the color filter layer 22 does not obscure the display image. Then, since the protective layer 44 does not come into contact with the color filter layer 22 on the boundary side of the transmissive display region T and the reflective display region R, the light leakage at this portion is suppressed to a low level by 139010.doc -17 - 201003204. Further, since the phase difference layer 42 and the protective layer 44 are formed in a strip shape across the adjacent pixels X, the inner surface phase difference portion 40 is formed in the same thickness without causing a layer thickness difference in the region between the pixels. As shown in Fig. 3(b), the phase difference layer core included in the inner surface phase difference portion 4A is not. The bottom surface is formed to have the same thickness, and has a flat surface 43 on the surface opposite to the element substrate 1A shown in FIG. 2, and has a flat portion 42a formed to have a substantially uniform thickness. The periphery of the portion 42a (from the cross-sectional view * is the both sides of the flat portion 42a) and the side wall portion 421 of the thickness change. When the phase difference layer 42 is formed by the conventional micro-shirt method of the conventional formation method, the end portion is formed in a slope shape in the processes of development, etching, and the like. Corresponding to the shape of the phase difference layer 42, the protective layer 44 is composed of a first protective portion 44a that covers the flat portion and is opened, and a second protection that covers the side wall portion 42b and abuts against the color filter layer 22. The portion 44b is configured. The spacer 50 is disposed on the first protection portion 4A that overlaps the flat portion 42a. ^The thickness of the liquid crystal layer can be accurately defined so as to be placed at a "higher position" with the flat surface of the flat portion 42 & which has a uniform thickness. Fig. 3 shows the arrangement position of the spacer 5〇. 5 〇 adjacent to each other, the region between the pixels P is provided at a position that does not overlap with the sub-pixel p. As described above, since the inner-surface phase difference portion (10) is formed in a strip shape, there is no layer thickness difference in the region between the pixels. Therefore, when the spacer 5 is disposed in the region between the pixels, the layer thickness can be surely controlled, and since the image is not blocked by the spacer 5G, the pixel aperture ratio can be improved. Continue to use the effect of the present invention. 4 is an explanatory view for explaining the effects of the present invention 139010.doc -18-201003204, and is a schematic cross-sectional view showing a liquid crystal display device in the vicinity of the inner surface phase difference portion spacer 50, and corresponds to Fig. 2 is a cross-sectional view in the field of view. In Fig. 4(a), for the sake of comparison, the protective layer 44 showing the inner phase retardation portion is not in contact with the counter substrate 2, and the display is provided with the present invention. The case of the structure of the invention. Figure 4(b) shows The spacer 50 is disposed on the side of the transmissive display region T by the center line 通过 extending through the center of the reflective display region r and extending in parallel with the arrangement direction of the pixel regions, and FIG. 4(c) shows that it is more than the medium to line C. The spacer 5 〇 is disposed on the side opposite to the penetration display region τ. Here, the material for forming the inner surface retard portion 40 and the spacer 50 will be described. As described above, the retardation layer 42 is made of a liquid crystal polymer. It is formed, but the general liquid crystal polymer used to form the retardation layer 42 has a hardness of a degree of pencil hardness, and its hardness is very low. In contrast, the protective layer 44 and the spacer 5 are made of acrylic acid. Resin and epoxy resin in terms of stray hardness, ί shows a high hardness of 4 Η to 6 。. The r pencil hardness referred to here is \ ^ by "JIS-K5600-5-4" general test method for coatings. - Part 5: Mechanical properties of the coating film - Section 4: Scratch hardness (pencil method)" The value obtained by the measurement. As shown in Fig. 4 (a), in the liquid crystal display device in which the protective layer 44 is not in contact with the counter substrate 20, it is assumed that the external force F is applied from the outside of the device. In this case, the stress is transmitted to the inner surface retardation portion 40 via the spacer 50, and the pressure is dispersed throughout the entire protective layer 44. Thus, the spacer 50 can be prevented from collapsing in the retardation layer 42. However, since the force transmitted to the phase difference layer 42 via the protective layer 44 is 139010.doc -19-201003204, the entire phase difference layer 42 is deformed, so that it is difficult to prevent the layer thickness of the liquid crystal layer 30 from changing. Further, as shown in Fig. 4(b), in the case where the protective layer 44 is in contact with the liquid crystal display device having the structure of the counter substrate 20, the stress is transmitted to the phase difference layer 42 via the spacer 5 and the protective layer 44 in the same manner. However, since the protective layer 44 is in contact with the opposite substrate 2 of the substrate surface, the second protective portion 44b covering the side wall portion of the phase difference layer 42 is supported against stress, and the stress is dispersed toward the opposite substrate 2. Therefore, the deformation of the phase difference layer 42 in the vicinity of the second protecting portion 44b can be suppressed. Further, as shown in Fig. 4(c), when the protective layer 44 is in contact with the liquid crystal display device ' of the structure of the counter substrate 20, and the spacer 5' is adjacent to the second protective portion 44b, it is more effective. When the external force ρ is applied from the outside of the apparatus in the arrangement of FIG. 4(b), the second protective portion 4 serves as a fulcrum 'the portion where the spacer 50 contacts the protective layer 44 as a force point, and the phase difference layer 42 The region which is planarly overlapped with the spacer 50 serves as an action point, and the retardation layer 42 is easily deformed in accordance with the principle of the lever. Therefore, although the deformation of the phase difference layer 42 can be suppressed as compared with the structure of Fig. 4(a), it is not called a filling knife. However, as shown in FIG. 4(c), when the second protecting portion 44b is disposed in contact with the spacer, since the distance between the fulcrum and the force point is short, the lever is difficult to work and the stress is more efficiently dispersed toward the opposite substrate 20. The deformation of the phase difference layer 42 can be prevented. In this manner, the retardation layer 42 having a lower hardness than the retardation layer 42 is protected by the protective layer 44 having a higher hardness, and one portion of the protective layer 44 is formed in contact with the counter substrate, and the deformation of the retardation layer 42 is effectively suppressed. Therefore, the layer thickness of the liquid crystal layer 30 can be maintained uniformly from 1390l0.doc -20 to 201003204. The spacer 5' described above may be provided in any one of the element substrate 1A or the opposite substrate 2'. Fig. 5 is a schematic cross-sectional view for explaining a portion where the spacer 50 is formed. As shown in Fig. 5 (4), the spacer 50 may be formed integrally with the protective layer on the protective layer 44. Further, as shown in Fig. 5(b), it may be integrally formed on the element substrate 10 side. As shown in Fig. 4, the present invention differs in the effect depending on the difference in the arrangement positions of the spacers 5〇. When the spacer layer 5 is formed in a portion where the high effect is achieved in advance when the protective layer 44 is formed as shown in Fig. 5 (4), good liquid crystal layer thickness management can be performed. Further, when the element substrate 1 is formed on the side of the element substrate 1 as shown in Fig. 5 (b), the phase difference layer 42 and the protective layer 44 are not exposed to the formation process of the spacer 5, and the spacer 50 can be provided. Therefore, in the step of forming the spacer 5, the phase difference layer "and the protective layer 44 are prevented from being damaged, and a highly reliable liquid crystal display device can be formed. According to the liquid crystal display device of the above configuration, the spacer (10) is disposed. In the case where the external layer is applied to the liquid crystal display device, the stress is applied to the liquid crystal display device, and the stress is dispersed in the retardation layer 42 via the high-hardness protective layer 44. In addition, since the second protective portion The peach is formed in contact with the color filter layer 22 on the basal plane. Therefore, in the case where an external force is applied, the second protective portion of the side surface of the retardation layer 42 is like a screen or a pillar to exert the support member work (4). The stress applied to the retardation layer 42 is diffused to the color concentrator layer 22 via the second protective portion 44b covering the side surface of the retardation layer 42. & In the above, the phase 139010.doc •21 · 201003204 can be suppressed. The cross-section of the dislocation layer 42 and the separation distance between the substrates can be well controlled by the spacers 5, thereby forming a liquid crystal display device capable of high-quality image display. In the present embodiment, the liquid crystal display device has a transflective liquid crystal display device that reflects the display region R and penetrates the display region in i pixels, and the phase difference layer 42 is provided on the reflective display in a planar manner. In the region R, the protective layer 44 covers the sidewall portion 42b other than the side surface of the phase difference layer 42 located in the boundary between the reflective display region r and the visible region τ in the pixel, and is in contact with the swatch filter layer 22 According to this configuration, since the protective layer 44 is in contact with the color filter layer 22 around the periphery of the reflective display region R, the second protective portion 44b is formed to be used as a support member for a wide area against stress. Further, in the present embodiment, a plurality of pixels X having the reflective display region R and the through display region T are arranged in a matrix, and are arranged in the respective pixels in the arrangement axis direction of the pixels. The reflective display region R of X, the retardation layer 42 and the protective layer 44 extend across the plurality of pixels and extend in a strip shape in the direction of the alignment axis. In addition, the protective layer 44 covers and forms the strip-shaped phase difference layer 42. The side surface of the phase difference layer 42 on the opposite side of the display region , is in contact with the color filter layer 22, and the spacer 50 is disposed at a boundary portion of the adjacent pixel region. Since the phase difference layer 42 and the protective layer 44 are formed continuously, Therefore, there is no portion where the layer thickness difference occurs between the pixels, and the spacer 5〇 can be disposed in the region between the pixels. Thus, the spacer 50 does not shield the display image, and the phase difference layer 42 and the protective layer 44 of such a shape are not shielded. It is also easy to form by patterning, thereby forming a liquid crystal display device i which is increased in design freedom and easy to manufacture. 139010.doc -22- 201003204 In the present invention, the spacer 5〇 is disposed at the center of the reflective display region R. Further, the center line extending in parallel with the arrangement direction of the pixel regions is on the opposite side to the penetration display region T. When the spacer 50 and the second protection portion 4 are disposed at positions close to each other, the spacer 50 and the second protection portion 441) are integrated to effectively resist stress, and can effectively resist external force from the outside of the liquid crystal display device F. The retardation layer 42 of the present embodiment has a flat surface 43 on the surface facing the element substrate 10, and the spacer 50 and the flat surface 43 are placed to overlap each other. When the phase difference layer 42 is formed by a patterning method or the like, the side surface of the phase difference layer 42 may have a slope shape and the thickness may not be uniform. However, by arranging the spacer 50 on the flat surface, a liquid crystal layer can be realized. Thick management. Further, in the present embodiment, the material for forming the protective layer 44 is an epoxy resin or an acrylic resin. However, any other forming material may be used as long as it exhibits a higher hardness than the retardation layer 42. In this case, when the thickness of the second protective portion 44b covering the side wall portion 42b of the retardation layer 42 is changed by the hardness of the material to be used, the material having a low hardness is used, and the thickness is formed by thickening. It is ensured to function as a supporting member of the protective layer 44. Further, in the present embodiment, the same material is used for the protective layer 44 and the spacer 5, in other words, the protective layer 44 and the spacer 5 are the same hardness, but even if the material of the (four) layer 44 is formed, the hardness is more than that of the spacer 5q. High formation materials are also fine. For example, an epoxy resin and an acrylic resin Japanese temple are used in the formation material of the spacer P total % 间隔 spacer 50, and the protective layer 44 is formed by using an inorganic substance such as oxygen cut (s1〇2) and gasification state iN). The hardness of the protective layer 44 can be made higher than the hardness of the intermediate P 50. The hardness of the protective layer 44 is more than the hardness of the spacer 5◦. 139010.doc -23- 201003204 The south time reduces the protective layer 44 itself from collapsing and deforming at the portion where the spacer 5 is disposed. Therefore, it is possible to more surely suppress the spacer 5 from collapsing in the phase difference layer 42' and further suppress the deformation of the phase difference layer 42. In the present embodiment, the retardation layer 42 includes the side wall portion 42b whose thickness is changed. However, if the retardation layer 42 is formed with high precision, the structure of the side wall portion 42b which does not have a gradient in thickness may be used. In this case, when the spacer 50 is disposed to overlap the protective layer 44 covering the side surface of the retardation layer 42 in a planar manner, the layer thickness management can be further reliably performed. Further, in the present embodiment, the spacer 5 〇 is disposed in the region of the adjacent two sub-pixels P&1, but it is more preferable to arrange it in the vicinity of the corner portions of the adjacent two pixels. Fig. 6 is a plan view showing the arrangement of the spacers. In the figure, the spacer 50A is disposed at a corner t of the sub-pixel p near t, and is in a direction in which the extension (4) of the inner surface phase difference portion 4G is parallel and orthogonal, and is not adjacent to the sub-pixel P. This position becomes the intersection of the areas between the pixels forming the pattern, with the symbol 50B, 50C.

When the spacer is disposed, when the extension of the inner phase difference portion 40 is < 1 A million and the orthogonal direction, the corpse e spacer is disposed in the sub-image *p 'one' , .仁疋' is placed near the intersection point = the object is (4) slightly horizontal or vertical, still not matched: on the sub-pixel p. Therefore, since a certain amount of deviation is allowed, the arrangement of the spacers is easy, which contributes to the efficiency and simplification of the coating process. (Second Embodiment) Hereinafter, a liquid crystal page device according to a second embodiment of the present invention will be described with reference to Figs. 7 to 9 .

The constituent elements common to the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated. Fig. 7 is a cross-sectional view showing a liquid crystal display device 2 of a second embodiment. As shown in FIG. 7, the liquid crystal display device 2 includes an element substrate 1A, a counter substrate 2A, a liquid crystal layer 30, and an inner surface phase formed by planarly overlapping a side surface of the liquid crystal layer 30 of the counter substrate 20 and the reflective display region R. The difference portion 7A and the spacer 5〇 disposed between the inner surface phase difference portion 70 and the element substrate 1A. The inner surface retardation portion 70 includes a phase difference layer 42 and a protective layer 74. The layer 74 is formed to cover the surface of the phase difference layer 42. The protective layer 74 covers the end portion of the phase difference layer 42 disposed in the non-display area DA, and the end portion of the phase difference layer 42 disposed at the boundary between the reflective display region R and the through display region T, and is in contact with the phase difference layer 42. The surface of the color filter layer 22 of the base surface is formed. The protective layer 74 is formed using a forming material that exhibits a higher hardness than the retardation layer 42 such as an acrylic resin or an epoxy resin. The protective layer μ can also be formed of yttrium oxide (Si〇2) and tantalum nitride (SiN). ) and other inorganic substances. Fig. 8 is a schematic view showing the vicinity of the inner surface phase difference portion 70 and the spacer 5'. Fig. 8(a) shows a perspective view. Fig. 8(b) shows a cross-sectional view, and Fig. 8(c) shows a plan view. Figure 8 is for the purpose of easily viewing the figure, so that it is reversed from Figure 7

TfC 〇 As shown in Fig. 8(a), the inner surface phase difference portion 70 is superposed on the reflective display region R included in the sub-pixel p, and extends across the adjacent pixel X to form a strip shape.垂139010.(j〇c -25- 201003204 One end in the direction perpendicular to the extending direction is located in the through-display area τ near the boundary of the reflective display area R, and the other end is planarly overlapped with the area between the pixels The display area D. The protective layer 74 included in the inner surface retardation unit 70 is superposed on the reflective display region R' and extends across the adjacent pixel χ to form a strip shape. The protective layer 74 covers the phase. The upper portion of the difference layer 42 , the side portion facing the non-display area DA, and the side portion facing the transmissive display area τ, in the non-display area DA and the transmissive display area ,, along the phase contacting the color filter layer 22 The end of the difference layer 42 is formed in contact with the color filter layer 22. As shown in Fig. 8(b), the protective layer 74 is a first protective portion 74a formed by covering the flat portion 42a of the phase difference layer 42; The side wall portion 42b on the non-display area DA side and the side wall portion 42b on the side of the display area T are formed to be in contact with the second protection portion 74b of the color filter layer 22. As shown in FIG. 8(c), The end portion of the protective layer 74 penetrates the visible region T side and is planarly overlapped The dry area T. The effect of the second embodiment will be described with reference to Fig. 9. Fig. 9 is an explanatory view for explaining the effects of the second embodiment, and shows the inner surface phase difference portion 70 and the spacer. A schematic cross-sectional view of the liquid crystal display device in the vicinity of 50, and a cross-sectional view corresponding to the field of view of Fig. 7. As shown in Fig. 9(a), the protective layer 74 also has contact with the pair on the side of the penetrating display region τ. The second protective portion 74b of the substrate 20 is applied. Therefore, when the external force F is applied from the outside of the liquid crystal display, the second protective portion 74b covering the side wall portion of the phase difference layer 42 is supported on the both sides by a screen. Since the object 50 and the protective layer 74 are conducted to the stress of the phase difference layer 42, the deformation of the phase difference layer 42 can be further reduced than that of the first embodiment. Further, since the second protection portion 74b Since both sides of the side wall portion of the retardation layer 42 are supported, as shown in FIG. 9(b), even when the spacer 50 is disposed on the side of the penetration display region T, the same as the case shown in FIG. 9(a) The deformation of the suppression phase difference layer 42 can be reduced. f 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶Since the penetrating display region τ side of the second protective portion 74b of the protective layer 74 is also in contact with the color filter layer 22, the deformation of the phase difference preventing layer 42 can be further reduced, and the spacer 50 can be relaxed. Further, the second protective portion 74b of the protective layer 74 that is in contact with the color filter layer 22 is also located in the transmissive display region τ, but even if the protective layer is planarly overlapped with the color filter layer 2 2 The location of the contact portion is also provided with a light-shielding structure. According to this configuration, even if the light-emitting genus is generated in the portion of the display region τ where the protective layer 74 is in contact with the color concentrator layer 22, since the light-shielding film can be shielded from light, the display can be improved as compared with the case where the light-shielding film is not provided. Comparison of images. (Third embodiment) Hereinafter, a liquid crystal display device according to a third embodiment of the present invention will be described with reference to Fig. 10'. The liquid crystal display device of the third embodiment is different from the liquid crystal display device of the second embodiment in that the protective layer is used as a thickness adjustment layer for adjusting the thickness of the liquid crystal layer in the transmissive display region and the reflective display region. Layers function as 'other structures are the same. The constituent elements common to the second embodiment 139010.doc -27. 201003204 are denoted by the same reference numerals, and the description thereof will not be repeated. Fig. 1 is a cross-sectional view showing a liquid crystal display device 3 of a third embodiment. As shown in FIG. 10, the liquid crystal display device 3 includes: an element substrate 1A, a counter substrate 20 liquid B layer 30, and a planar layer of the liquid crystal layer 30 side of the counter substrate 20 and the reflective display region R. The inner surface retardation portion 80 and the spacers 5 disposed between the inner surface retardation portion 80 and the element substrate 1A. The inner surface retardation portion 80 includes a phase difference layer 42 and a protective layer 84. The protective layer 84 covers the surface of the retardation layer 42 to form an end portion of the retardation layer 42 disposed on the non-display region DA, and a phase difference disposed at the boundary between the reflective display region R and the transmissive display region T. The end of the layer 42 is formed in contact with the surface of the color filter layer 22 of the base surface of the phase difference layer 42. The protective layer 84 is formed using a material which exhibits hardness toward the phase difference layer 42 such as an acrylic resin or an epoxy resin. The material for forming the protective layer 84 may also be an inorganic material such as yttrium oxide (Si〇2) or tantalum nitride (SiN). Further, the protective layer 84 may have a structure in which a layer formed of an acrylic resin, an epoxy resin or the like is stacked on a layer formed of an inorganic substance such as yttrium oxide (Si〇2) or tantalum nitride (SiN). Similarly to the above-described embodiment, the inner surface retardation portion 80 has a layer thickness L2 of the liquid crystal layer 3A in the reflective display region R that is thinner than a layer thickness of the liquid crystal layer 30 in the transmissive display region τ. The layer thickness L2 of the liquid crystal layer 30 in the reflective display region r and the layer thickness L1 of the liquid crystal layer 30 in the transmissive display region T are adjusted to a specific thickness. The transflective liquid crystal display device is for the reflective display area 139010.doc -28- 201003204. The incident light penetrates the liquid crystal layer 30 twice, and the incident light penetrating the display region τ penetrates only the liquid crystal once. Layer 30. Therefore, in both the reflective display region R and the transmissive display region T, in order to obtain a high-intensity image display, it is required to impart a penetrating liquid crystal layer 3 to each of the reflective display region R and the transmissive display region τ. The phase difference of the light is optimized so as not to cause a difference in light transmittance. In order to optimize the phase difference of the light imparted to the liquid crystal layer 30 in each of the reflective display region R and the transmissive display region, the layer thickness L2 of the liquid crystal layer 30 in the reflective display region R should be worn. The layer thickness L1 of the liquid crystal layer 3A in the transparent display region 1 forms a specific thickness. For example, in the reflective display region R, the phase difference imparted to the light penetrating the liquid crystal layer 30 is λ/4 wavelength, which will penetrate the display region ,, and impart a phase difference of light passing through the liquid crystal layer 3 as a two-wavelength In the case of the moon, the layer thickness l 1 of the liquid crystal layer 3 穿透 in the display region τ is set to be twice as large as the layer thickness L2 of the liquid crystal layer 30 in the reflective display region R. The layer thickness L2 of the liquid crystal layer 30 in the reflective display region R is controlled by the width of the spacers 5〇. Further, the layer thickness L1 of the liquid crystal layer 3A penetrating through the display region is the thickness (L2) of the spacer 50, and the thickness of the inner surface phase difference portion 80, that is, the thickness of the phase difference layer 42 and the protective layer 84. The thickness N is controlled. In order to form a thickness of the layer thickness L1 of the liquid crystal layer 30 penetrating the display region ,, the thickness (m+n) of the inner surface phase difference portion 8〇 should be accurately formed. Here, the phase difference layer 42 is formed to impart a phase difference of λ/2 wavelength in the transmitted light. By the retardation layer 42 and the liquid crystal layer 30 in the reflective display area, it is possible to form a λ/4 wavelength which is suitable for the wide band of the reflection display in the reflection display area ruler. However, since the thickness Μ of the phase difference layer 42 is formed by the material of the phase difference layer 42 having a refractive index anisotropy of 139 〇 1 〇 (j〇c • 29· 201003204), the thickness m of the phase difference layer 42 is m. It is difficult to form an arbitrary thickness. Therefore, in the present embodiment, the protective layer 84 is substantially formed to adjust the layer thickness of the liquid crystal layer 3G in the inner surface retardation portion 8 (). The protective layer 84 can be easily adjusted than the phase difference layer 42. The thickness is formed by the thickness (4). Therefore, by setting the thickness N of the protective layer 84 by the thickness (M+N) of the inner surface retardation portion 80, the liquid crystal layer 3 in the reflective display region R can be formed. = thickness L2 and the layer thickness u of the liquid crystal layer 3 in the transparent display region are adjusted to a specific thickness. For example, the layer thickness of the liquid crystal layer in the display region τ is formed to form a liquid crystal layer in the reflective display region R When the layer thickness L2 of 3() is twice as large as the thickness L2 of the protective layer 84, the thickness N of the protective layer 84 is set to correspond to the difference between the height (L2) of the spacer 5〇 and the thickness Μ of the phase difference layer 42. This ignores the thickness of the alignment film 18 and the alignment film 28. According to the structure' In the inner surface phase difference portion 8, the layer thickness l 2 of the liquid crystal layer 3 反射 in the reflective display region R and the layer thickness L1 of the liquid crystal layer 30 in the transparent display region T are substantially adjusted by the protective layer 84, and The phase difference of the light to be transmitted is set by the phase difference layer 42. In other words, the thickness and the phase difference of the inner surface phase difference portion 80 can be independently controlled. Therefore, the layer thickness management of the liquid crystal layer 30 can be performed more accurately and easily. Further, in the present embodiment, as in the second embodiment, the protective layer 84 covers the boundary between the reflective display area and the through-display area. The side surface of the side surface of the retardation layer 42 is in contact with the surface of the color filter layer 22. However, as in the first embodiment, even if the layer 139010.doc -30·201003204 is formed, the layer 84 is covered in the reflective display region R. The side surface other than the side surface of the phase difference layer 42 that penetrates the boundary of the display region τ may be in contact with the surface of the color filter layer 22. Even with such a configuration, the same configuration as in the embodiment can be obtained. (Modification) In the above embodiment, the inner surface retardation portions 40, 70, 80 form a strip-shaped retardation layer 42 and a strip-shaped protective layer 44, 74, 84 is formed across a plurality of pixels. Fig. 11 is a schematic plan view showing a modification of the inner surface phase difference portion 40 in the first embodiment, and corresponds to Fig. 3(c). The inner surface phase difference portion 40 of Fig. 11(a). Each of the pixels X is provided with a phase difference layer 42, and the mother pixel includes a protective layer 44 that surrounds the periphery of the phase difference layer 42 and is in surface contact with the substrate. When formed, the protective layer 44 against stress increases when an external force is applied' Therefore, the deformation of the phase difference layer 42 can be prevented, and the liquid crystal layer thickness management can be performed. Fig. 11(b) further subdivides the structure of Fig. 11(a) into each sub-pixel ρ. Each of the sub-pixels P is provided with a phase difference layer 42, and each of the sub-pixels includes a protective layer 44 surrounding the periphery of the phase difference layer 42 and in contact with the substrate surface. Such a structure can more strongly prevent deformation of the phase difference layer 42 and can perform accurate liquid crystal layer thickness management. In the same manner as in FIG. 11(b), the phase difference layer 42 is disposed in each of the sub-pixels p, and the strip-shaped protective layer 44 covering the plurality of phase difference layers 42 is formed. A protective layer 44 is formed between the adjacent retardation layers 42 in contact with the base surface. Such a structure can obtain the same effect as that of Fig. (b). However, it is not necessary to have a fine patterning of the protective layer 44 of 139010.doc -31 - 201003204, which is easy to manufacture. In the configuration of the inner surface phase difference portion 4A shown in FIG. 11, the portion of the inner surface phase difference portion 40 having a difference in thickness due to the shape of the inner surface phase difference portion 40 is increased, and the spacer is suitably disposed in the non-display region. The flat part of the 5 inch is reduced. At this time, by arranging spacers in the image display area and shielding the light-shielding film as needed, the liquid crystal layer thickness can be surely controlled after the influence on the image quality is reduced. In addition, FIG. 12 is a schematic plan view showing a modification of the inner surface phase difference portions 7A, 8B in the second embodiment and the third embodiment, and corresponds to FIG. 8(4). Picture. Further, the structures shown in Figs. (9) and (4) correspond to the structures shown in Figs. 4(4), (b), and (4), respectively. In the case where the above-described modified example is applied to the second embodiment and the third embodiment, the same effects as those in the case of applying the above-described modified example in the first embodiment can be obtained. [Electronic device] Next, an embodiment of the electronic device of the present invention will be described. Fig. 3 is a perspective view showing an example of an electronic apparatus of the present invention. The mobile phone measurement shown in Fig. 13 includes the liquid crystal display device of the present invention as a small-sized display portion 13〇1' and includes a plurality of operation instructions (10), a reception side, and a transmission port 1304. Thereby, it is possible to provide a mobile phone system including a display unit having excellent display quality by the liquid crystal display device of the present invention. The liquid crystal display device of the above various embodiments is not limited to the above, and is also suitable for use as an electronic book, a projector, a personal computer, a digital still camera, a television image receiver, a viewfinder type, or a monitor direct view type photography 139〇l〇.
